In the present embodiment, the control unit 3 confirms that the preceding vehicle has started based on the collection result of the own vehicle surrounding information collecting unit 8 or that the lighting state of the traffic signal ahead has changed to other than “stop”. Detecting that the vehicle 2 is in the above-described startable situation.

  The storage unit 6 stores various data used for starting warning output control, and stores a notification timing determination table 35, a notification level determination table 37, and a map DB 39. The map DB 39 stores map information and is used for specifying a location where the vehicle 2 is currently located and road information around the location.

FIG. 3 is a diagram showing the notification timing determination table 35.
The notification timing determination table 35 is data for advancing or delaying the timing for outputting a start warning (hereinafter referred to as “notification timing”) O based on the driver state P and the vehicle state Q. It is.
More specifically, in the present embodiment, the notification timing O is determined according to the probability that the driver D recognizes that the current situation is in a startable situation where a start operation for starting the vehicle 2 may be performed. Variable. That is, when this probability is low, the notification timing O is earlier than normal (“middle” in the figure) (“early” in the figure). Conversely, when this probability is high, the notification timing O is It is delayed (“Late” in the figure). In the notification timing determination table 35, such a relationship between the probability and the notification timing O is defined.

  In the present embodiment, the probability that the driver D recognizes the startable situation is determined by the control unit 3 based on the driver state P. As shown in FIG. 3, the driver state P that is the determination material includes an operation P1 of the driver D (“apparatus operation” in the figure) P1 for the devices not involved in the driving operation, and the driver D dozing. P2 is used.

For example, when the device operation P1 is detected (in the drawing, device operation P1 = "Yes"), since the driver D is performing an action unrelated to the start operation, there is a probability that the start possible situation is not recognized. high. In addition, even when the driver D's snoozing P2 is detected (in the figure, the snoozing P2 = “Yes”), there is a high probability that the startable situation is not recognized.
On the contrary, when neither the device operation P1 nor the dozing P2 is detected (in the drawing, the device operation P1 = “none” and the dozing P2 = “none”), the driver D can start. Therefore, the notification timing O is set to be delayed from the normal time.
On the other hand, when only one of the device operation P1 and the snooze P2 is detected (in the figure, only one of the device operation P1 and the snooze P2 is “No”), the driver D Since the probability of recognizing the startable situation is relatively low, the notification timing O is set to be earlier than usual.

  In the present embodiment, the notification timing O is also set in accordance with the length of time that the driver D takes from the start to the completion of the start operation (hereinafter referred to as “start operation required time”) when the vehicle 2 is stopped. Variable. That is, when the time required for the start operation is long, the notification timing O is earlier than usual, and conversely, when the time required for the start operation is short, the notification timing O is delayed. Stipulates such a relationship between the time required for the start operation and the notification timing O.

In the present embodiment, the time required for the start operation is determined by the control unit 3 based on the vehicle state Q, and the state of the operation target operated during the start operation is used as the vehicle state Q that serves as the determination material. A parking brake, a shift lever, and a foot brake are used as the operation target.
That is, as shown in FIG. 3, the parking brake operating state is acquired (hereinafter referred to as “parking on Q1”). As for the operation state of the shift lever, a state where the shift lever is positioned other than neutral and reverse (back) (hereinafter referred to as “shift position Q2”) is acquired. As for the operation state of the foot brake, a state in which the foot brake is operating (hereinafter referred to as “foot brake on Q3”) is acquired.

  In the operation state of the parking brake, the shift lever, and the foot brake, the state where the start operation required time is the shortest is an operation state where the number of operations required for the start operation is the smallest. As shown in FIG. 3, the operation state is such that the parking brake is not activated (parking brake on Q1 = “N”) and the shift lever is located in a position other than neutral and reverse (shift position Q2 = “Y ]) And the foot brake is operating (foot brake on Q3 = “Y”). In this operation state, the notification operation O is delayed because the time required for the start operation is short.

  Note that the combinations shown in FIG. 3 of the driver state P, the vehicle state Q, and the notification timing O are merely examples, and can be changed as appropriate based on various conditions and other factors.

FIG. 4 is a diagram showing the notification level determination table 37.
The notification level determination table 37 is setting data for changing the intensity level (hereinafter referred to as notification level U) of the stimulus given to the driver D by the start warning output based on the situation at that time. In the present embodiment, the notification level U is set to the normal level (the higher the influence of the state in which the start operation of the own vehicle is not performed (that is, the stop or start delay of the own vehicle) on the surroundings (particularly other vehicles such as the rear vehicle T2) In the figure, it is higher ("High" in the figure), and conversely, the smaller this effect is, the lower the notification level U is than normal ("Medium" in the figure) (in the figure, "Low"). Further, when this influence is not substantially present, the start warning output itself is unnecessary (notification level U = “unnecessary”). The notification level determination table 37 defines this relationship between the influence and the notification level U.

  In the present embodiment, the influence of the state in which the start operation of the host vehicle is not performed on the other vehicle is determined by the control unit 3 based on the peripheral information collected by the host vehicle peripheral information collecting unit 8. As the surrounding information T for determining the influence, the current lane information of the own vehicle, the presence / absence of the rear vehicle T2, the presence / absence of the traffic signal immediately before the own vehicle, the presence / absence of the front vehicle T5, and the congestion information of the road R are used. ing.

For example, when the host vehicle is not located in the lane of the road R (“T1 on the road” = “N” in FIG. 4), there is almost no influence on other vehicles even if the host vehicle continues to stop.
On the other hand, when the own vehicle is located in the lane of the road R (“on road T1” = “Y”), when the rear vehicle T2 exists, the stop of the own vehicle affects the rear vehicle T2. There is a probability. In this case, in particular, when the road R is congested (“T3 during traffic jam” = “Y”), and when the host vehicle is located in front of the traffic signal (“T4 before signal” = “Y”). If the vehicle does not start quickly in accordance with changes in traffic signals, it will be a factor in prolonging traffic jams and will have a large effect on the rear vehicle T2. Therefore, at this time, the notification level U is set to the highest.

  On the other hand, if the host vehicle is not T3 before the signal ("T4 before signal" = "N") and there is no preceding vehicle T5 ("front vehicle T5" = "N"), any reason other than the traffic rule There is a high probability that the driver D stops intentionally (for example, when the vehicle stops on a shoulder or when there is a vehicle trouble). Therefore, in this case, since it is estimated that the other vehicle travels avoiding the own vehicle, it is determined that there is almost no influence, and the notification level U is set to “unnecessary”.

  Note that the combination of the peripheral information T and the notification level U in FIG. 4 is merely an example, and may be appropriately changed based on various conditions and other elements.

FIG. 5 is a diagram illustrating an example of the notification level U. As illustrated in FIG.
As shown in the figure, the difference in the notification level U is realized by three combinations of the vibration intensity of the seat of the driver D, the sound output mode, and the display output mode.
For example, the vibration intensity of the sheet increases as the notification level U increases.
Further, the start warning sound (“guidance voice” in the figure) is output only when the notification level U is “high”, and at this time, it is output together with the notification alarm sound.
When the notification level U is “low”, the start warning is displayed in a simple form (for example, an icon or comment) on a part of the display (for example, “simple notification display” in the figure), When the notification level U is “medium” and “high”, a start warning is displayed on the full screen (“display full screen notification” in the figure).
When the notification level U is “unnecessary”, none of the vibration of the seat, the sound output, and the display output are performed.

FIG. 6 is a flowchart showing the notification process of the notification device 1.
When the control unit 3 determines that the host vehicle is stopped based on the detection result of the vehicle state acquisition unit 9 (step S1: YES), the control unit 3 detects a startable situation in which the host vehicle 2 may start.
That is, the control part 3 determines the presence or absence of the front vehicle T5 based on the collection information of the own vehicle periphery information collection part 8 (step S2). When there is a forward vehicle T5 (step S2: YES), when the forward vehicle T5 has started (step S3: YES), a startable situation has been reached.
On the other hand, when there is no forward vehicle T5 (step S2: NO), the control unit 3 determines that the own vehicle is a traffic signal signal ("red signal" in Japan) based on the own vehicle surrounding information collection unit 8. Whether or not the vehicle is stopped is determined (step S4). When the host vehicle is stopped by a traffic signal (step S4: YES), when the traffic signal changes to something other than “stop” (“green light” in Japan) (step S5: YES), It means that it is possible to start.

  If there is no preceding vehicle T5 (step S3: NO) and the host vehicle is not stopped by a traffic signal (step S4: NO), the host vehicle temporarily stops while moving. Rather, it is estimated that the vehicle is stopped for some reason such as parking. Under such circumstances, since it is not necessary to output a start warning to the driver D, the control unit 3 ends the process.

  When the vehicle is ready to start while the host vehicle is stopped, a start warning is output in principle. In order to control the output of this start warning (that is, whether there is notification, notification timing O, and notification level U). The control unit 3 executes the following process.

  That is, the control unit 3 detects the driver state P and the vehicle state Q based on the information of the vehicle information collection unit 7 (step S6), and the notification timing according to the driver state P and the vehicle state Q. O is set based on the notification timing determination table 35 (step S7). In addition, the control unit 3 acquires the peripheral information T from the own vehicle peripheral information collecting unit 8 (step S8), and sets the notification level U corresponding to the peripheral information T based on the notification level determination table 37. (Step S9).

Here, in this embodiment, when the own vehicle 2 turns right or left after the start, the start warning is changed according to the surrounding situation at that time.
That is, when the winker is operated (step S10: YES, the control unit 3 determines the traveling direction (right turn direction or left turn direction) indicated by the winker based on the information of the vehicle surrounding information collection unit 8. ) Is determined whether or not there is an event (hereinafter referred to as a “progress inhibition event”) that can inhibit the progress after the departure to (step S11). The presence of an oncoming vehicle at the time of a right turn in left lane driving can be mentioned.
When there is a progress inhibition event (step S11: YES), the control unit 3 changes the start warning to a notification with the content of “contents for prompting attention to progress inhibition events” added to “contents for prompting to start”. (Step S12).

Next, the control unit 3 starts measuring elapsed time in order to output a start warning at the notification timing O set in step S7 (step S13).
During this timing, the control unit 3 detects the presence or absence of the start operation of the driver D (step S14), and when the driver D performs the start operation before reaching the notification timing O (step S14: YES). Since it is not necessary to notify the driver D of the start warning, the control unit 3 does not output the start warning and ends the notification process (step S15).

  On the other hand, when it is determined that the start operation has not been performed before the elapse of S until the notification timing O is reached without detecting the start operation of the driver D (step) (step S14: NO), the control is performed. The unit 3 causes the notification unit 4 to output a start warning at the set notification level U (step S16). The control unit 3 continues the start warning until the start operation of the driver D is detected (step S17: NO), and when the start operation is detected (step S17: YES), the control unit 3 displays the notification unit 4 Is stopped (step S18), and the notification process is terminated.

  Next, a specific example of the start warning output by the notification process will be described.

FIG. 7 is an explanatory diagram of the first specific example.
In this specific example, the vehicle 2 is located in the lane R1 of the road R, the lane R1 includes a front vehicle T5 and a rear vehicle T2, and the front vehicle T5 is stopped. It is.
In this case, when the preceding vehicle T5 starts traveling (FIG. 6, step S3: YES), in steps S6 to S9 of the notification process, the notification timing O corresponding to the driver state P and the vehicle state Q, and the surroundings A notification level U corresponding to the information T is set.

  For example, as shown in FIG. 8A, when the driver D points the line-of-sight direction F toward the audio device 70 and operates the audio device 70, “present” of the device operation P <b> 1 is detected as the driver state P. The In this case, it takes time until the driver D recognizes the startable situation (start of the front vehicle T5), and there is a high probability that the other vehicle such as the rear vehicle T2 will be hindered. Moreover, if the start of the own vehicle is delayed, there is a possibility that the rear vehicle T2 may be alerted by a horn or the like. Therefore, in this case, as specified in the notification timing determination table 35 of FIG. 3, the start warning notification timing O is advanced earlier than usual.

  Further, for example, as shown in FIG. 8B, when the driver D is firmly facing the line-of-sight direction F, the driver state P is “nothing” for the device operation P1 and “nothing” for the dozing P2. Is detected. In this case, the driver D recognizes the startable situation (start of the forward vehicle T5) and has a high probability of not requiring the start warning of the notification device 1. Therefore, in this case, as specified in the notification timing determination table 35 of FIG. 3 described above, the start warning notification timing O is delayed more than usual. After that, when the driver D performs a start operation before the notification timing O arrives, the output of the start warning is canceled and is not output by the processes of steps S14 and S15 of the notification process.

  As a result, the driver D recognizes the startable situation, and the start warning is not output even though the start operation is actually performed, and the troublesomeness for the start warning is reduced. Further, the higher the probability that the driver D is aware of the startable situation, the later the notification timing O, the more cases where the start operation is performed before the notification timing O, and the start warning is actually output. The case is also suppressed, and the troublesomeness is further reduced. Even if there is a high probability that the driver D is aware of the startable situation, if a start operation is not actually performed by the notification timing O, a start warning is output and the driver D is started. Can be encouraged.

FIG. 9 is an explanatory diagram of a second specific example.
This specific example is a case where the own vehicle 2 is located in the lane R1 of the road R, is stopped by the signal of the traffic signal V in front of the traffic signal V, and there is a rear vehicle T2. .
In this case, when the signal of the traffic signal V changes (FIG. 6, step S5: YES), the driver state P and the vehicle state Q are changed to steps S6 to S9 in the notification process as in the first specific example. The corresponding notification timing O and the notification level U corresponding to the peripheral information T are set.
In this specific example, since the vehicle surrounding information collection unit 8 also collects signal changes of the traffic signal V as surrounding information, even if there is no preceding vehicle T5, the startable situation (signal of the traffic signal V) Change) is promptly detected, and a start warning can be output at the notification timing O corresponding to the driver state P and the vehicle state Q and the notification level U corresponding to the surrounding information T.

FIG. 10 is an explanatory diagram of a third specific example.
In this specific example, the own vehicle 2 is located in the lane R1 of the road R, is stopped by the traffic signal V in front of the traffic signal V, and the vehicle 2 turns right from the operating state of the winker 71. Is predicted.
In this case, when the signal of the traffic signal V changes (FIG. 6, step S5: YES), as in the first and second specific examples, in steps S6 to S9 of the notification process, the driver state P and A notification timing O corresponding to the vehicle state Q and a notification level U corresponding to the surrounding information T are set.
Further, in this specific example, in steps S10 to S12 of the notification process, if there is an event (progress inhibition event) that can inhibit the vehicle 2 from proceeding in the right turn direction, The start warning is changed to a notification with the content of “content to call attention to an inhibition event”. In this specific example, since the oncoming vehicle 2A that is traveling in the lane R2 that the own vehicle 2 is scheduled to cross is approaching, a notification for recognizing the presence of the oncoming vehicle 2A is “notice to the progress inhibition event”. Is added to the start warning.
This prevents the driver D from starting the vehicle 2 with insufficient confirmation of the surroundings in response to the “prompt to start” by the start warning in a situation where the progress inhibition event has occurred. Is done.

  As described above, according to the present embodiment, the following effects can be obtained.

  In the notification device 1 of the present embodiment, since the control unit 3 controls the output of the start warning according to the driver state P, the state of the driver D is reduced so as to reduce the annoyance that the driver D feels about the start warning. It is possible to control the output of the start warning in accordance with.

  In the notification device 1 according to the present embodiment, the driver state P includes a state relating to the probability that the driver D recognizes that the driver may perform a start operation, and the control unit 3 determines the probability. The start warning output is controlled accordingly. Thus, according to the probability that the driver D recognizes the start operation, the start warning is output in an appropriate output manner that can reduce the troublesomeness of the start warning while the driver D is surely recognized. Can output.

  In the notification device 1 according to the present embodiment, the control unit 3 controls the output of the start warning according to the vehicle state Q, and therefore outputs the start warning in an appropriate output manner as described above according to the vehicle state Q. it can.

To do. Thereby, according to the influence on the periphery, the start warning can be output in the appropriate output manner as described above.

In the notification device 1 of the present embodiment, the control unit 3 is at least one of a notification timing O that is a timing for outputting a start warning and a notification level U that is a level of stimulation that the start warning output gives to the driver D. Control one.
Accordingly, a start warning can be output at the appropriate notification timing O and / or the notification level U as described above according to an appropriate combination of the driver state P, the vehicle state Q, and the surrounding information T.

  In the notification device 1 according to the present embodiment, the control unit 3 does not output a start warning when a start operation is performed before the start warning is output. D does not feel annoying.

In the notification device 1 of the present embodiment, when the driver D is in a situation where the driver D may start the vehicle while the host vehicle is stopped, the start operation is performed by the driver D. Inspired by
As a result, the driver D can recognize from the start warning output in the appropriate output mode as described above that the vehicle is ready to perform the start operation. , You can start smoothly.

  In the notification device 1 of the present embodiment, the control unit 3 detects based on the peripheral information T that the situation in which the start operation may be performed is detected, and thus detects the situation only by the start of the forward vehicle T5. The situation can be detected with higher accuracy than the conventional technology.

In the notification device 1 according to the present embodiment, when the surrounding information T indicates that there is an event that may hinder the progress of the host vehicle after the start, the control unit 3 performs a start operation and attention to the event. A notification for prompting is output as a start warning.
Thereby, after making the driver | operator D recognize the event concerned, start operation can be performed.
